FOLDING BOX.

Specification of Letters Patent.

Application filed March 1, 1910.

Patented Oct. 18, 1910. Serial No. 546,592.

To all whom it may concern:

Be it known that I, JOSEPH W. PUTNAM, a citizen of the United States ,ofAmerica, residing at Grand Rapids, in the county of Kent and State ofMichigan, have-invented certain new and useful Improvements in FoldingBoxes; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the artto which it appertains to make and use the same.

My invention relates to improvements in folding boxes, and moreparticularly to improvements in the styleof folding box shown in myPatent No. 940,941, dated November 23, 1909, and its object is toprovide a box that will fold downmore compactly when out of use; that isless likely to become broken where the paper is folded; to provide a boxbetter adapted .for shelf use, and to provide the same with various newand useful features, hereinafter more fully described and particularlypointed out in v the claim, reference being had to the accompanyingdrawings, in which:

igure 1 is a perspective of a box em: bodying my invention as it appearswhen opened out for use; Fig. 2 the same partially folded; Fig. 3 adetail of one corner in plan viewv as shown in Fig. 1; and, Fig. 4 thesame in vertical section through the end.

. Like numbers refer to like part-s in all of the figures.

1 represents the bottom of the box; 2 the sides, and 3 the ends, eachbeing a parallelogram in form and of a single integral piece ofmaterial, preferably of pasteboard or heavy paper. The ends'are providedwith an upper extension 4 folded inward and adapted to engage the sidesat the inner upper corners and hold the same in vertical position. Thisfolded extension also forms a stiffening for theends, and I prefer toleave the same without fastening whereby 1t normally stands slightlyinclined inward at the bottom, as indicated in Fig. 4. Each end of theend portion is also extended in a substantially right angled triangle asat 5, and extends around the corner of the box, and upon the outside ofthe same when opened out and is foldably secured at the hypotenuse by amarginal portion 6 secured to the sides by staples 8 and provided with adiagonal crease on the hypotenuse as at 7 between the parts 5 and 6, itbeing adapted to fold along this crease when the sides are turned downupon the bottom and the ends turned inward, as illustrated in Fig. 2. Bythis construction, the device readily folds without breaking and alsofolds inward in a very compact form within the horizontal dimensions ofthe bottom portion 1. When opened out for use, all that is necessary isto pull the ends up to place and the box automatically locks in open position. The ends present a smooth plane surface which may be labeled andthe boxes placed side by side on a shelf with the outside extensions 5and 6 covered.

lVhat I claim is A folding box, comprising a bottom portion, sides andends integral therewith and adapted to fold inward upon the same, upperextensions on the ends folded inward and engaging the sides to hold thesame vertical,

triangular extensions on the ends folded around the ends of the sideswhen the box is open, and a portion on the hypotenuse of each extensionsecured to the side portion.

In testimony whereof I aflix'my signature in presence of two witnesses.
